Port
Physical test port of the analyzer. You can define independent loss parameters for all
ports.

identifies the physical port.
Loss at DC / Loss at Freq / Freq for Loss
Defines the one-way loss parameters for the transmission line at the selected port. The
loss can be modeled as the sum of a constant and a frequency-dependent part. The
total loss is approximated by an expression of the following form:

This means that all three loss parameters enter into the calculation of the loss.
See also Chapter 8.6.1.2, "Definition of Loss Parameters " , on page 260.
Note: The entered parameters define the loss for a signal traveling in one direction
through the transmission line. To account for the propagation in both directions, the
magnitude shift of a reflection parameter due to a given loss is twice the magnitude
